FURROW PLOW AND ROLLER.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed August 15, 1906. Serial No. 330,658.

` irrigation, the' object being to provide a de- .shaft bearings; and

vice of this character, that will be comparatively light to draw overthe ground to form the ditches and to smooth the banks, sides and bottomof the ditches.

l willdescribe a furrow plow and roller embodying my invention and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding figures.

Figure 1 is a sectional elevation on the line of Fig` 2 of a furrow plowand roller embodying my invention; Fig. 2 is a front elevation thereof,partly in section, on the line y-fy of Fig. 1, and Fig. 3 is a frontview of the roller.

The main frame of the machine comprises side sills 1 connected at therear end by a cross bar 2 and about the middle portion by a cross bar 3;the side sills extend forward from the cross bar 3 .as indicated at 4,and these forward extensions are connected near the front end by a crossbar 5 to which the draft tongue has connection. As here shown, the drafttongue consists cf a member 6 and a :member 7, having vertical swingingconnection with the member 6, but is held from lateral movement withrelation thereto. The member 6 is mounted to swing on a bolt l S whichpresses downward through a bearing 9 secured to the cross bar 5, andmounted to swing on this bolt below the cross bar 5 is a yoke 10 inwhich a steering roller 11 has its extended upward from he shaftbearings and to rigid connection with the member 6 of the tongue, arebraces 12, Obviously, by means of the roller 11 the machine, that is therear portion thereof, may be steered or guided as desired, by thelateral movement of the tongue. Extended upward from the side sills hereshown as at the junction of said sills with the intermediate cross bar,are standards- 13 connected 4 of the sills. points 17 are attached theseplow points have convergent side edges which extend practically to apoint parts in all the at the top by across bar 14; and forward lofthese standards is a plow beam 15 which is vertically movable at itsends in the guide clips 16 secured to said forward projections To thisbeam 15 the plow at the lower end. -As a means for raising and loweringthe plow points as occasion may require, rods 18 are extended upward topivotal connection with arms 19 extended forward from a rock shaft 2Ohaving bearings in blocks 21 attached to the standards 13.

Extended rearward from the rock shaft 2O is an operating lever 22 whichcarries a spring-pressed pawl 23 for engaging between any air of teethon a segment-rack 24 secure( at the upper end to the cross bar 14 and atthe lower end to a tool-box 25.

The operating lever 22 extends to a convenient position to be operatedby a driver on the seat 26 supported on a standard 27 secured to the topof the tool-box. This -toolbox as here shown has at its rear end aswinging cover 28. Arranged rearward of the plow points is the smoothingroller which also forms a support for the rear portion of the machine.This smoothing roller preferably consists of two sections 29, 30, eachhaving at its center, and in alinement with a plow point, a smoothingring 31 which corresponds in shape in cross-section, to the shaft of theplow points. At opposite sides of these ring portions 31 the rollersections are cylindrical as indicated at 32.

The shafts of the roller sections, at the outer ends, have bearings inboxes 33 secured to the sills 1; at the inner ends the shafts have.bearings in a box 34`secured to a central, longitudinally,disposed sill35.

In operation,

will cut a 'V-'shap'ed ditch in which the portions 31 of the smoothingroller will follow to smooth the walls, and the dirt thrown upward andoutward by the plow points will be smoothed or flattened by the plainlcylindrical portions 32 of the roller.

it will be noted that the plow beam 15 is connected to the cross chains36, permitting a free up and down movement of said plow beam, butcausing the draft to be exerted directly thereon.

Having thus described my invention l claim as new and desire to secureby Letters Patent:

\ as the machine. is drawn` along, the plow points roo bar 5 by means ofIIO A machine for the purpose set forth, cornrising a frame, plows suported in the frame, a roller journaled in the frame behind each of theplows, said rollers comprising a 5 central ring corresponding in crosssection to the shape of the plow pointI and a cylindrical ortion uponeach side of the ring, said cylinrical portions being of lesser diameterthan the ring, and said central ring being directly 1o behind the plowpoint, whereby said ring will enter and smooth the furrow formed by thel plow, and the cylindrical portions will press and smooth the groundadjacent to the edges of the furrow.

In testimony whereof I have signed my i 5 name to this specification inthe presence of two subscribing witnesses.
